Freddos to go by the inflation price (15p)

From 2000 - 2005 there were these small chocolate frogs that were called Freddos. Back then they were 10p per frog. But in 2010 Cadbury wanted more money and decided to increase these god like chocolates from 10p to 17p. Within just 7 years, the price jumped from 10p to 25p. MORE THAN 2p a year. Based on inflation the price for these chocolates should only be 15p but Cadbury boosted it up to 25p. It is predicted that by 2030 Freddos will cost 38p rather than 20p which it should be.
